Unfortunately, at the time of the explosion, generally accepted ideas about the structure of the Universe were far from modern ones. At that time, astronomers could not yet measure distances to celestial bodies, so the bright spot in the Andromeda constellation, also known as M31, was considered an ordinary reflection nebula on the outskirts of the Milky Way.
Meanwhile, the emergence of new and more powerful telescopes and the development of space technologies gradually changed the situation. As early as the 1920s, observations by Edwin Hubble and other astronomers demonstrated that the Andromeda Nebula is another galaxy, very similar to the Milky Way.
